Frenolepis longicornisj Ltr,, ^ . 



" A commonly occurring and very widely distributed ant 

 in British Guiana. To be found as an inhabitant of most 

 liouses. Is especially fond of sugar and dead insects of all 

 kinds. I have also frequently observed it to infest steamers 

 and other craft which call at the })ort of Georgetown. 

 Formicarium usually constructed just beneath the surface of 

 the soil at the base of posts, walls, &c., or in crevices in 

 wood-work ; they are usually small. Houses may be 

 successfully cleared of them by exposing a mixture of 

 molasses and arsenic or by hunting for the nests and 

 destroying them with carbon bisulphide.'' 



A well-known cosmopolitan species.
